To all 'whom it may concern:

Be it known that I, JOHN TWADDLE, a subject of the King of the United Kingdom of Great Britain and Ireland, and resident of 18 Chalmers street, Glasgow, Scotland, have invented certain new and useful Improvements in Filing-Boards, of which the following is a specification.

This invention relates to piling boards.

At present it is usual, in iron works, to use wooden piling boards for the introduction of the piles into the scrap furnaces, which boards are, of course, consumed in the furnace, each board being used only once, and it has also been proposed to use metal boards or plates which remain in the furnace and are absorbed into the pile.

Under the present invention I provide a piling board consisting of a metal plate or sheet which can be used over and over again thus doing away with the usual well known piling boards adapted to be consumed in the scrap furnace and thus effecting a great saving.

In order that the improved piling board may be used over and over again it must, of course, be made of metal and must be provided with means whereby it may be inserted into the furnace with the material thereon and be then withdrawn in such manner as to leave the material behind.

Preferably in carrying out this invention the piling board consists of a metal plate or sheet having the one end or edge thereof formed or provided with a hook or hooks or equivalent adapted to be engaged by horns or projections or the equivalent provided on the peel, the arrangement being preferably such that the. peel is allowed to slip out a certain distance before engaging and withdrawing the plate or sheet.

In order that the invention may be clearly understood I have hereunto appended eX- planatory drawings which show by way of illustration or example some modes of constructing the piling board.

Figure 1 is a side view showing one form of the device. Fig. 2 is a similar view but showing the piling board partially withdrawn. Fig. 3 is a plan view of the peel shown at Figs. 1 and 2. Fig. 4: is a plan view of the piling board shown at Figs. 1 and 2. Fig. 5 shows (in side and plan view) a modied form of piling board. Fig. 6 shows (in side and plan view) a modified form of peel adapted for use in conjunction with the piling board shown at Fig. 5. Fig. 7 shows (in side and plan view) another modified form of piling board. Fig. 8 shows (in side and plan view) a form of peel for use in conjunction with the piling board shown at Fig. 7.

In the form shown at Figs. 1 to 4; the piling 'board' consists of a sheet metal plate a; having a pair of extensions or lugs o, which are turned upward at 1 and extend downwardly to the hooked parts b2 at the eXtreme ends thereof. The peel c is provided with a pair of laterally extending horns or projections c1 adapted to engage the said hooked parts b2 and to so draw the plate a from beneath the pile Z of material with which the furnace is being charged. The plate a is shown (in dotted lines at Fig. 1) with an upturned portion e adapted to serve as a rest for a pusher bar adapted to be used in the case lof very heavy piles in order to assist the man handling the peel.

In the arrangement shown at Figs. 5 and 6 the peel c2 is made with a recess e3 having an undercut portion o4 adapted for the reception of a depending or hook portion b3 on the sheet metal piling board of, the arrangement being such that the peel is allowed a certain amount of slip before commencing to withdraw the board.

Figs. 7 and 8 show an arrangement in which the piling board b5 is provided, on its underside, with a circular projecting portion 796 adapted to engage an elongated recess 06 in the peel c5 so that the piling board with the pile thereon may be turned around on the peel to any desired angle thereby permitting of the piles being arranged in the furnace in any desired position, while the formation of the projecting portion Z9 and of the recess o6 permits of the desired slip of the piling board before the withdrawal thereof.

Claims- 1. Means for use in the introduction of the piles into scrap furnaces, consisting of a flat metal plate for the pile, a peel for supporting the plate and conveying it with the pile into the furnace, projecting means on the peel, and projections on the plate for engaging the said projecting means after a partial withdrawal of the peel in any angular position, so that the plate may be withdrawn from beneath the pile by the peel.

2. Means for use in the introduction of the piles into scrap furnaces, consisting of a flat metal plate for the pile, a flat peel for supporting and conveying the plate and pile into the furnace, projecting means on the peel, and rigid hooks on the plate adapted to engage the said projecting means on the peel after its partial withdrawal and in any angular position, so that the plate may be thereafter withdrawn from beneath the pile.

3. Means for use in the introduction of the'piles into scrap furnaces, consisting ofa iiat metal plate for kthe pile, a flat peel for conveying the plate and pile in upright position into the furnace, said plate being detachableV from the peel and covering it, means for the engagement or' the plate. with the peel permitting the peel to be partially withdrawn from beneath the plate, and

l means on the plate for the support of a push bar adapted to prevent the withdrawal of the plate during said partial Withdrawal of the peel, said plate discharging the pile over its forward edge, after the withdrawal of the peel.

4. The combination of a peel and a piling Y copies of'tls patent may be obtained for ve cents each, by addressing the being spade-shaped and provided with an Y abutment, and the piling board consisting of a flat rectangular metal plate having a rigid hook at its rear end for engaging with said'abutment with the peel in any angular position and while the front edge of the piling board overlaps that of the peel, said piling board having an upwardly extending tail piece for coacting with a push bar.
